Therefore, in the conventional mold making equipment, a push-up device such as a cylinder for pushing up the lower die base is separately provided on the lower die mounting base, and therefore the conventional mold making equipment is used. Has a problem in that it becomes large in size and expensive in a complicated structure.
The upper mold is generally placed on the lower mold and replaced together with the lower mold when replacing the lower mold. The present invention has been made in view of the above circumstances, and the lower die mounting base can be easily and reliably mounted on the lower die mounting base without separately providing a device for lifting the lower die base on the lower die mounting base. It is an object of the present invention to provide a device that can be replaced with a new one.

[0004]

In order to achieve the above-mentioned object, a horizontal split mold exchanging device according to the present invention is a horizontal split mold having a lower mold attached with a mold pushing mechanism, which is installed under a mold making facility. A device for exchanging with respect to a mold mounting base, which is an extrusion plate mounted on the lower mold mounting base to push out the mold pushing mechanism, and an extrusion plate operation mounted on the lower mold mounting base to operate the extrusion plate. Means, a lower die base removably attached to the lower die mounting base and having a lower die attached to the upper surface thereof, a plurality of rollers rotatably attached to the outer surface of the lower die base, A claw member that is removably attached to the extrusion plate side of the lower die base and is engageable with the extrusion plate, and is tiltably attached to the lower die attachment base, and when it is upright, is it on the lower die attachment base? Wherein the elevated the lower mold die base equipped with a, and a pair of rails which can be mounted through the rollers.

[0005]

In the apparatus constructed as described above, in order to remove the lower die base and the like from the lower die mounting base, first,
After the claw member is projected toward the push-out plate side, the push-out plate actuating means is operated to raise the push-out plate, and the push-up plate raises the claw member and the lower die base. Next, when the rail is erected, and then the pushing plate operating means is reversely operated to lower the pushing plate, the rollers are placed on the rail as the pushing plate is lowered, and as a result, the lower die base is lowered. It will be separated from the mounting base and will be able to move horizontally. Further, the attachment to the lower die mounting base such as the lower die base can be performed by performing the reverse operation to the above-mentioned operation.
